SPIDERS OF THE ORB- WE AVER GENUS PARAWlXiA IN 
AMERICA (ARANEAE: ARANEIDAE) 



HERBERT W. LEVM 

Abstract. Parawixia are Neotropical, nocturnal orb 
weavers related to Acanthepeira, Eriophora, Wag- 
neriana, and Wixia. The relationship is based mainly 
on synapomorphie character states of inale and fe- 
male genitalia. 

Of the 26 species of Parawixia found in collections, 
10 are new, four are known only from males, six from 
females. There are 24 new synonyms of species and 
subspecies naiives, Most Parawixia species are found 
in the Amazon area primarily, and in Central Amer- 
ica and eastern Brazil Many species probably build 
webs in the canopy. The social nianduti spider {Para- 
wixia InstriafaX which made such an impression on 
Darwin, belongs to Parawixia. 

INTRODUCTION 

Among the" interesting spiders found in 
South America by Charles Darwin, as re- 
ported in 1839 in The Voyage of the Bea- 
gle, was a social orb- weaver species. *'. , . 
1 found near St. Fe Bajada [present day 
Parana] many large black spiders, with 
ruby -coloured marks on their backs, hav- 
ing gregarious habits. The webs were 
placed vertically, as is invariably the case 
with the genus Epeira: they were separat- 
ed from each other by a space of about 
two feet, but were all attached to certain 
common lines ^ which were of great length, 
and extended to all parts of the commu- 
nity. In this manner the tops of some large 
bushes were encompassed by the united 
nets. Azara [F. de Azara, 1809, Voyage 
dans rAmeriqiie meridionale] has de- 
scribed a gregarious spider in Paraguay, 
which Walckenaer thinks must be a The- 
ridion, but probably it is an Epeira, and 
perhaps even the same species with mine, 
I cannot, however, recollect seeing a cen-

tral nest as large as a hat, in which, during 
autumn, when the spiders die, Azara says 
the eggs are deposited. As all the spiders 
which I saw were of the same size, they 
must have been nearly of the same age. 
This gregarious habit, in so typical a genus 
as Epeira, among insects, which are so 
bloodthirsty and solitary that even the two 
sexes attack each other, is a very singular 
fact/' 

It is a reflection on the current status of 
spider studies that this spider, though 
named bistriata in 1836 by the Swiss trav- 
eler Rengger, and frequently mentioned 
(Busk irk, 1981), has never been illustrated 
before. In 1932 Mello-Leitao placed hist fi- 
at a in Eriophora and was followed by the 
catalogers Roewer and Bonnet. Mello-Lei- 
tao did not provide illustrations and on 
receiving some specimens 15 years later 
did not recognize them and gave them a 
new name. Only recently Shear (1970) 
considered that Darwin's spider may have 
been a Cyrtophoray an orb- weaver genus 
with some social species. Several investi- 
gators (Fowler and Diehl, 1978; Fowler 
and Gobbi, 1988a,b) studied the behavior 
but were uncertain as to whether there are 
one or two species that are social. Radcock 
(1932) realized that a species described and 
illustrated previously by TuUgren from 
Bolivia was a social spider also found in 
Paraguay as reported by Carter (1928), the 
collector of Badcock's specimens. 

This paper is part of the ongoing study 
of Neotropical orb weavers (Herman and 
Levi, 1971; Harrod, Levi, and Leiben- 
sperger, 1991; Levi, 1968, 1971, 1985, 1986, 
1988, 1989, 1991a,b). The primary pur- 
pose of my revisions is to help determine

species within a given genus, in this case 
Parawixia. Such determinations are need- 
ed because spider species are often of eco- 
nomic importance or biological interest 
(e-g., Parawixia histriata), A secondary 
function is to provide information aiding 
in the understanding of evolutionary re- 
lationships within the genus. Sequestering 
this information may be easy in small fam- 
ilies but is much more difficult in large 
and diverse families. Studies on the evo- 
lution of small families less diverse than 
the orb weavers have been published based 
on an understanding of a few species in 
the genus (Coddington, 1986). 

Before a genus has been revised, it may 
only be known by its most common species 
or by the type species to w hich the generic 
name is attached. However, the type spe- 
cies is often the most aberrant member of 
the genus, and has been placed in its own 
genus specifically because of unusual char- 
acters that may not occur in more "aver* 
age ' congenerics. Also, in large diverse 
families, the study of all species is neces- 
sary to determine generic-level characters. 

To take examples, when 1 first worked 
on Eriopliora in 1970, 1 assumed that Para- 
wixia V>elonged to the same genus perhaps 
as a species group of Eriophora. Careful 
study of Parawixia showed this assumption 
to be erroneous because^ several characters 
were found to be apomorphies for Para- 
wixia only (see below). In another study, 
1 characterized the genus Wixia as lacking 
a long scape (Levi, unpublished key). I 
have since found that this absence is only 
true for Xearctic species; many Neotrop- 
ical species (which otherwise share apo- 
murphies with Nearctic Wixia and can 
fairly be cons itle red congeneric) do have 
a long scape (Levi, in prep,). These char- 
acters wert* not elucidated until revisions 
of the genera in question hud been done* 

Fvohitionary analyses of generic rela- 
tionships cannot be made until tlie relevant 
genera themselves have bt m revised and 
the limits of the individual genera defined. 
Any premature analysis would have to be 
revised with each successive generic re- 



vision. 1 am currently completing work on 
a sub-group of the family Araneidae, char- 
acterized by the presence of a palpal para- 
median apophysis and including the gen* 
era Parawixia, Eriophora, Acanthepeira, 
Wagneriana, Alpaida, Wixia, Acacesia, 
and Cijclosa. When the final members of 
this group, Wixia and Acacesia (both 
manuscripts in preparation), are revised, 
comparison and evolutionary analysis of 
this group w ill be possible, 

METHODS AND MATERIALS 

The methods used are the same ones as 
those used in previous papers on Neotrop- 
ical orb weavers. Relative eye sizes were 
measured by comparing their diameter in 
profile with that of the anterior median 
eyes. The distance separating the eyes of 
the anterior row^ was measured relative to 
the diameter of the anterior median eyes 
in profile; and that the posterior row to the 
diameter of the posterior median eyes, A 
forthcoming paper on the genus Wixia w ill 
describe these methods in some detail. 

The specimens used came from the fol- 
low in g collections,

Parawixia F. P.-Cambridge 

Parawixia F. P. -Cambridge, 1904; 487, Type species 
by original designation Epeira de strict a O. P.- 
Cambridge, 1889. 

Diagnosis, Parawixia can be distin- 
guished by the epigynum which, unhke 
that of Wagneriana, has a scape as long 
as or longer than the width of the base 
and, unlike that of Eriophora, has the scape 
originating from the posterior margin of 
the base (Figs. 9, 19, 74). The distal end 
of the paramedian apophysis in Parawixia 
males is in the shape of a disk with a finger 
along the distal margin and extending be- 
yond it (Figs. 7, 26, 39). In Wagiwriana 
the paramedian apophysis is L-shaped; in 
Wixia and Acacesia the paramedian 
apophysis is a straight prong. Tn Acanihe- 
peira and Eriophora the paramedian 
apophysis is a separate sclerite. Unlike that 
of Eriophora, the palpal patella of Para- 
wixia males has only one macroseta. 

Coloration, lateral eyes, and abdomen 
shape are distinctive. There are dark marks 
between median and lateral eyes (Figs. S, 
4, 12), paired dark spots on the carapace 
(Figs. 24, 62), and a pattern of paired light 
patches on the sternum (Fig. 6). In some 



species, these marks are missing. The lat- 
eral eyes are on the sides below tubercles 
(Figs, 2-5), The spherical to trapezoidal 
abdomen has 2 to 6 pairs of lateral tuber- 
cles and xisually 2 to 3 tubercles in a me- 
dian line posteriorly (Figs. 12, 17). 

In collections from Mexico and Guat(^- 
mala, where the ranges of the two genera 
overlap, females of Parawixia can be sep- 
arated from those of Nearctic Acanthe- 
peira (Levi, 1976; fig. 12) that also have 
paired spots on the carapace, but have an 
abdominal median anterior tubercle lack- 
ing in Parawixia (Figs. 12, 17, 49). 

The shape of the embolus of the male 
palpus and its attachment (soft, lightly 
sclerotized tissue with a small hematodo- 
cha) may be an autapomorphy. The round 
to trapezoidal shape of the tubercle-bear- 
ing abdomen is an autapomorphy of Para- 
wixia species, as are the paired light marks 
on the sternum (Fig. 6, Table 1). 

Description. Carapace orange to brown 
with one or more pairs of spots and char- 
acteristic dark marks betw een median and 
lateral eves and behind the lateral eyes 
(Figs. 12, 17, 37), There are few hairs on 
the carapace. Parawixia hist rial a, how- 
ever, has a hairy carapace and lacks the 
paired spots. Chelicerae of all are darker 
distally than proximally. The endite and 
labium rnav be dark. The sternum is dark 
with pairs of lighter patches (Fig. 6) except 
in P. baracoa, F. undulata, and P. bistria- 
ta. The coxae are orange to brown w ith 
dusky patches and the legs have indistinct 
dark rings. The dorsum of the abdomen is 
variable in individuals of each species but 
the venter has a species-characteristic pat- 
tern. It is black w ith a distinctive median 



* There are exceptions. 

** l\ bistriata and £. nephiloides (Levi, 1971) have a large macroseta and a smaller one on the male palpal 
patella.

while patch (Fie. 31). pairs of white marks 
(Figs. 18. 44: 14'0.147)Vnther distinctive 
markings always different from those of 
related species. 

The anterior median eyes are the larg- 
est, the lateral eyes the smallest. The pos- 
terior median eyes ma) be on a shght 
swelling in Paratvixia^ but are not in Wag- 
neriana, Acanthepeira, or Eriophora. In 
Wixia (in prep.) and Acacesia (in prep.) 
the posterior median eyes are on a swelling 
with tlie eves directed toward the sides. 

Parawixia have a subspherical to trap- 
ezoidal abdomen with four to 15 tubercles, 
three or four pairs on the sides toward the 
anterior and middle, one pair posterior on 
the sides, and two to three single tubercles 
in a posterior median line (Figs. 12, 17), 
All individuals of a species have the ab- 
domen about the same shape. Adult Para- 
wixia hist hat a females lack these tuber- 
cles, but im matures and males frequently 
have three lateral pairs and a faint pos- 
terior median tubercle (Fig. 157), Only 
rarely (in immature and some adult female 
P. audax) does Parawixia have a median 
anterior tubercle as in Acanthepeira. 

Male coloration is as in females. In males 
the cephalic region is narrow (Figs. 3, 4) 
as in males of EriopJiora and Wagneriana. 
It is not narrow in males of Acanthepeira. 
The abdomen is the same shape as in the 
female but smaller (Fig. 62). The palpal 
patella has only one macroseta, except in 
F, bisiriata, which has a second smaller, 
white mac^roseta. The endite has a tootli 
facing a tubercle on thc^ proximal end of 
llic palpal ienuir (Figs. 4, 6). There is al- 
ways a hook on the distal margin of the 
first coxa (Fig. 6) fitting into a groove on 
the second femur. The fourth and some- 
times third coxae and trochanters of Par- 
awixia males (except in F. audax. P. un- 
dulata, and P. hist r lata) have one or more 
macrosetae (Fig. 6), as in males of Wag- 
neriana, Eriophora, Acanthepeira^ and 
Wixifl. The second til>ia is armed with 
macrosetae and thicker than the first tibia. 
As in related genera, the palpus has a para- 



median apophysis. The base of the median 
apophysis, just above the radix, is usually 
modified to resemble a depressed oval w ith 
teeth or keels along its margin (Figs. 7, 26, 
142, 149, 156), a synapomorphy shared 
with Eriophora and important for sepa- 
rating species of Parawixia. In Wagner- 
iana and Wixia the base is sclerotized, 
sometimes with a tooth; in other genera it 
usually is not modified or sclerotized. The 
embolus is cone- or bullet-shaped (Fig. 7) 
in all but P\ kochi. In Eriophora it is of 
various shapes. The terminal apophysis of 
the Parawixia palpus is partly fused to the 
embolus, as in Wagneriana and Erioph- 
ora. {Acanthepeira lacks a terminal 
apophysis.) This fusion is probably a ple- 
siomorphy. 

Variation. The dorsal abdominal pat- 
tern and coloration differ among individ- 
uals of the same species. The number of 
macrosetae on the third and fourth tro- 
chanters of males is variable and com- 
monly differs on left and right sides of the 
same specimen. 

Relationships. Parawixia is closest to£r- 
iophora (Levi, 1971) and Acanthepeira 
(Levi, 1976). (he long scape of the epigy- 
num is a synapomorphy with Acanthe- 
peira and Eriophora species (in Acanthe- 
peira the scape is relatively short). Rut in 
all Eriophora species the scape originates 
from the anterior margin, and folds back 
to point posteriorly. The shape of the para- 
median aptjphysis of the male palpus 
(which is attached to the conductor) and 
of the abdomen are autapomorphies for 
the genus Parawixia. The tubercles of the 
lateral eyes and the pairs of dark spots on 
the carapace are synapomorphies with 
species of Acanthepeira. The dark streaks 
between median and lateral eyes may also 
be found in Eriophora edax. The usually 
black underside of the abdomen mav have 
a median white patch or distinctive pairs 
of light or white patches (Figs. 13, IS, 31, 
79) that are also found in species of Wixia, 
The tubercles on the abdomen are ho- 
mologous with those of Wagneriana and

Acanthepeira, therefore synapomorphic. 
However, in Wagneriana, the abdomen is 
rectangidar, longer than wide and often 
with a tail above the spinnerets. Macro- 
setae on the third and fourth coxae and 
trochanters of males (not always present), 
presence of a paramedian apophysis, and 
ack of distal hematodocha are synapo- 
morphies of these various genera: Para- 
wixia, Acanthepeira, Wagneriana, Wixia, 
Eriophora, Alpaida, Vcrnicosa, and others 
(Table 1), 

Natural History, The best known spe- 
cies is F. audax y which makes a loose large 
web and sits in the hub, cephalic region 
down, or in a rolled-leaf retreat, one to 



two meters above the ground. Most species 
probably live in the canopy and are rarely 
collected. Parawixia bistriata is social and 
makes webs fairly high up, commonly on 
telephone poles. All individuals in a colony 
are of the same age and size and during 
daytime they cluster together in a shared 
retreat (Plate 1; see below). 

Note. When working on Eriophora in 
1970 1 thought that Parawixia might be a 
synonym of Eriophora (Levi, 1971), but 
this is not the case (see above). The two 
genera are related. No additional species 
of Eriophora have been found (only one 
doubtful male from Peru), 

Distribution. Parawixia is found

just molted, with its epigynum not com- 
pletely hardened. 

Description. Female holotype. Cara- 
pace orange with brow n spots, Chelicerae 
orange distally brown. Labium, endites 
brown. Sternum dusky with pairs of clear 
patches. Coxae, legs orange with brown 
spots and rings and white setae. Dorsum 
of abdomen whitisli, brown on sides {Fig. 
12); ventt^r black with a pair of white spots 
anterior to spinnerets (Fig, 13). Eyes small. 
Posterior median eyes 0.8 diameter of an- 
terior medians, laterals 0.7 diameter. An- 
terior median eyes L6 diameters apart. 
Posterior median eyes 2 diameters apart. 
A!)d(>men with 13 tubercles: four pairs on 
sides and five posterior (Fig. 12). Total 
length 12 mm. Carapace 4.2 mm long, 3.8 
wide. First femur 4.8 mm, patella and tibia 
5.8, metatarsus 3.5, tarsus 1.3. Second pa- 
tella and tibia 5.4 mm, third 3.0, fourth 
4,6. 

Variation. Total length of females 12.0 
to 13.1 mm. The illustrations were made 
from the holotype. 

Diagnosis. The long posterior median 
plate of the epigynum has a ventral con- 
striction (Fig, 10) unlike that of any otlier 
species.

fig. 13, 6, not 14, 2. Male holotype from Bugaba, 
Chiriqui Prov., Panama, not in BMNH, not in HEC,

pi. 46, figs. 9, 10, 2, i. Roevver, 1942: 870. Bonnet, 
1958: 3339. 

Note. O. P.-Cambridge (1889) de- 
scribed a male and figured a male and a 
female, the female of a Wixia. F. P. -Cam- 
bridge (1904) illustrated the male with the 
correct female and considered the 1889 
male, now lost, to be the type and the 
correct female a "deuterotvpe." The Brit- 
ish Museum has specimens erroneously 
marked as types, which come from Gua- 
temala, not from the type locality in Pan- 
ama. Keyserling (1892) had seen these 
Guatemala specimens, which were also ex- 
amined by F. P. -Cambridge; the male un- 
doubtedly is the same species as the lost 
male holotype.

made from specimens from Guatemala; 
Figures 20, 22, from a female from Chia- 
pas. 

Note. Males and females were collected 

together in Guatemala. 

Diagnosis, Females differ from those of 
other species by having the greatest width 
of the posterior median plate being about 
equal to the greatest width of the lateral 
plates in posterior view^ of the epigynum 
(Figs. 21, 22). Males difter fruui those of 
other species by the strongly curved me- 
dian apophysis of the palpus (Fig, 26). 

Natural History. The Mexican speci- 
mens were collected in a cloud forest.

of black spots. Chelicerae, labium, endites 
dusky orange. Sternum clear orLUige with- 
out the usual light patches, Coxae orange, 
without dusky or darker marks; legs or- 
ange, ringed and spotted with black. Dor- 
sum of abdomen with black folium (Fig. 
30); venter black with a central white spot 
and a pair of smaller white spots in front 
of spinnerets (Fig. 31). Eyes large. Poste- 
rior median eves 0.9 diameter of anterior 
medians, laterals 0.7 diameter. Anterior 
median eyes their diameter apart, their 
diameter from laterals. Posterior median 
eyes their diameter apart, two diameters 
from laterals. Abdomen with four tuber- 
cles (Fig. 30), Total length 7.5 mm. Car- 
apace 3.5 mm long, 2.5 wide. First femur 
3.9 mm, patella and tibia 4.7, metatarsus 
2.9, tarsus 1,1. Second pattella and tibia 4.1 
mm, third 2.5, fourth 3.8. 

Variation, Total length of females 6.2 
to 10.7 mm. The coloration of all four spec- 
imens is similar but the Ecuadoran spec- 
imen has the posterior median plate less 
depressed anteriorly. Figures 27-31 were 
made from the holotype. 

Diagnosis. This species differs from otli- 
ers by having marks on the cephalic re- 
gion, lacking marks on the sternum, and 
by having only four abdominal tubercles 
(Fig. 30). The posterior median plate of 
the epigynum (Fig. 28) is diamond -shaped, 
unlike that of F. honesta (Fig. 15) and P. 
deslricta (Figs. 21, 22).

Description. Female from Depto. Cau- 
ca, Colombia, Carapace orange with darker 
spots, darker between median and lateral 
eyes. Sternum dusky orange with three 
pairs of lighter patches. Coxae orange with 
darker streaks; legs dark orange w ith dusky 
patches and indistinct dusky rings. Dor- 
sum of abdomen orange brown (Fig. 37); 
venter V)lack w ith a median light spot (Fig. 
38). Carapace relatively flat and low. Pos- 
terior median eyes 0,9 diameter of anterior 
medians, laterals 0.8 diameter, Anterior 
median eyes their diameter apart. Poste- 
rior median eyes their diameter apart. Ab- 
domen with 10 tubercles (Fig. 37). Total 
length 1L7 mm. Carapace 4,8 mm long, 
3.6 wide. First femur 5.7 mm, patella and 
tibia 6.9, metatarsus 4.1, tarsus 1.3. Second 
patella and tibia 6.3 mm, third 3.6. fourth 
5.6. 

Male from San Pedro, Colombia. Color 
as in female with distinct, median white 
patch on black venter of abdomen. Pos- 
terior median eyes 0.7 diameter of anterior 
medians, laterals 0.7 diameter. Anterior 
median eyes their diameter apart. Poste- 
rior median eyes their diameter apart. 
Fourth trochanter with two macrosetae. 
Second femur w ith a ventral row of macro- 
setae. Abdomen as in female. Total length 
8.2 mm. Carapace 4.3 mm long. 3.5 w ide. 
First femur 5,1 mm, patc^lla and tibia 6.3, 
metatarsus 3.9, tarsus 1.5, Second patella 
and tibia 4.9 mm, third 2.9, fourth 4.5. 

Note. Males and females have not been 
collpcted together but both sexes have been 
collected in San Pedro, Colombia, and their 
distribution is similar. 

Variation. The proportions of the epigy- 
nimi of the synt\ pe illustrated are similar 
to those of the female from Cauca. In no 
two individuals is the posterior median 
plate exactly alike (Figs, 33-35), and the 



pAnAWixiA^Levi

terminal apophysis of males differs slightly 
among individuals. Some individuals have 
only four tubercles on the abdomen: two 
widely separated median anterior tuber- 
cles, and two median posterior, close to- 
gether. Of the three syntypes of Epeira 
rimosa, the epigynum of the one recently 
molted is illustrated (Figs. 32, 33, 36), Fig- 
ures 36 to 38 were made from a specimen 
from Costa Rica; Figure 34 was made from 
a specimen from Cauca, Colombia, and 
Figure 39, from Magdalena Dept., Colom- 
bia. Total length of females 9.7 to 14 mm, 
of males 6.2 to 9.5. 

Diagnosis. All specimens of this species 
have a median white patch on the black 
venter of the abdomen (Fig. 38). Females 
can be separated from those of P. destricta 
and P. barbacoas by the wide posterior 
median plate and relatively narrow^ lateral 
plates in posterior view of the epigynum 
(Figs. 33-35). Males can be distinguished 
by the strongly curved median apophysis 
and from P. destricta by the shape of the 
embolus (Fig. 39), 

Natural History. Most specimens come 
from high elevations, above 1,000 m, but 
a few^ are from low elevations. The pair 
from Ecuador came from a rain forest in 
Tinalandia.

Diagnosis. The long, vase-shaped pos- 
terior median plate of the epigymim (Fig. 
41) and the relatively short scape are di- 
agnostic (Figs. 40, 42), The male differs 
from that of P, nesopJiiJa by having four 
white spots on the underside of the ab- 
doiiien and details of the palpal sclerites.

female holotype and a male from Yucatan 
have been illustrated. 

Diagnosis. Females have a pair of more 
or less distinct bulges on the ceplialic re- 
gion (Fig. 49). The female can be sepa- 
rated from other Central American Para- 
wixia species by the relatively long, flat 
scape of the epigynum (Figs. 46, 48). In 
some individuals the scape has been bro- 
ken off. The male can be separated by the 
shape of the relatively small terminal 
apophysis, the large conductor, and the 
shape of the median apophysis (Fig, 51). 
This is the only Parawixia species known 
from the Greater Antilles,

house, 1973, 1974 (W, Kberharcl), in MC]Z. The 
specific name Is a noun in apposition after the Span- 
ish worti for hntise. 

Descripfion, Male holotype. Carapace 
orange, wilh paired spots, sides of thoracic 
region dusky, dark dnsk\' between median 
and lateral eyes. Sternum dusky orange 
with three pairs of t It ar orange patches. 
Coxae dusky orange; legs orange to mostly 
gray and black. A w hite transverse line on 
dorsimi of abdomen (Fig, 53) between an- 
terior tubercles and a folium in middle; 
venter dusky with two pairs of tiny white 
spots in center. Posterior median eyes 0.7 



diameter of anterior medians, laterals 0/6 
diameter. Anterior median eyes 0.9 di- 
ameter apart. Posterior median eyes their 
diameter apart. Fourth trochanter w ith tw o 
short macrosetae. Third femur onlv with 
a distinct row^ of ventral macrosetae. Ab- 
domen with five tubercles: one pair an- 
terior and three posterior in a row^ (Fig.

mm long, 3.4 wide. First legs missing. Sec- 
ond patella and tibia 4.5 mm, third 2,7, 
fourth 4.0. 

Note. The male was first thought to be 
that of P. barhacoaSy for which only tlie 
female is known, but they differ in col- 
oration of the carapace, of the sternum, 
and of the venter of the abdomen. 

Diagnosis. The peculiar shape of the 
median apophysis of the palpus (Fig. 52) 
distinguisfies the male from males of other 
species.

Description, Male holotype. Carapace 
yellowish with a dusky patch on each side 
extending posteriorly from below lateral 
eyes to anterior of thoracic region, and 
lacking paired dark spots (Fig. 55). Che- 
licerae yellowish with a dusky streak. En-

Diagnosis. The first tarsus only, on both 
sides, is minute. This may be a character 
of the species or a malformation of the 
male. The C- shaped embolus, which ap- 
pears to have a cap, and the distal lobe of 
the median apophysis make the palpus dis-

imens from Napo, Ecuador, lack the me- 
dian ventral white spot. The male holotype 
and a female from Barro Colorado Island, 
Puuama, were illustrated. 

Diagnosis. The abdomen of the females 
is trapezoidal (Figs. 59, 62), Females can 
be separated from similar species by the 
small, square, posterior median plate of 
the epigynum (Fig. 57). The palpus of the 
male differs from that of any other species 
in having a pointed median apophysis 
bearing a small knob on its margin (Fig. 
61).

Yariation. Total length of females 9,0 
t(^ 14,4 mm, of males 8.0 to 8,8, All illus- 
trations were made from Barro Colorado 
Island specimens. 



Diagnosis, The 13 abdominal tubercles, 
with anterior laterals double (Fig. 66), and 
the narrow^ median posterior plate of the 
epigynum, bordered on each side by con- 
vex margins of the lateral plates (Fig. 64), 
distinguish this species from the Brazilian 
P. inopinaia (Fig. 70). The male differs 
from F, gnat e male nsis (Fig, 45) and P. 
inopinata (Fig. 73) by the shape of the 
terminal apophysis and median apophysis 
of the palpus (Fig, 68), and from F. gua- 
temalensis by having a median w hite patch 
on the underside of the abdomen. 

Natural History. Parawixia nesophila is 
apparently found in forested areas. A male 
was found in Costa Rica in leaf litter.

Note. Male and female are matched on 
the basis of their similar abdomen shape 
(Fig. 72). Also the genitalia of both sexes 
(Figs. 69-7 L 73) resemble those of P. ne- 
saphila. 

Diagnosis. Both the male and the fe- 
male are close to the Panamanian P. ne- 
sophila. The female differs by having a 
bottle-shaped posterior median plate of the 
epigynum (Fig. 70). The male differs by 
having h>nger prongs of the median 
apophysis of the palpus (Fig. 73),

diameter of anterior medians, laterals 0.7 
diameter. Anterior median eyes their di- 
ameter apart. Posterior median eyes tlieir 
diameter apart. Abdomen with 15 tuber- 
cles: four pairs on sides, one small anterior 
median, and six posterior. Of these, one 
pair and four medians above spinnerets. 
Posterior tubercles with cap (Fig, 78), To- 
tal length 9,6 mm. Carapace 4.7 mm long,

Note, Males and females were collected 
together in Mato G rosso, and both were 
collected at a second locality in Mato G ros- 
so although not together.

most posterior tubercle above the spinner- 
ets may be present or absent. Figures 74- 
79 \\ ere made from a female from Dia- 
mantina, Minas Gerais, Brazil; Figure 80 
was made from a male from Meta Dept,, 
Colombia, 

Diagnosis. Females can be separated 
from most Paniwixia species by the shape 
of the scape, which has a knob above its 
tip. From P. monticola they are separated 
by another feature of the epigynum: the 
lateral plates overhang the median plate, 
forming a slit with almost parallel edges 
in posterior view (Figs, 75, 76). The male 
can be separated from males of most spe- 
cies by the three macrosetae on the fourth 
trochanter, by having the median apoph- 
ysis distally bilobed, and having proxi- 
mallv a small tooth just above the radix 
{Fig. 80), 

Nat lira! History. A male was collected 
by sweeping shrubs in Colombia, and from 
a forest in Argentina-

Male from Minas Gerais, Brazil. Color 
as in female. Posterior median eyes 0.7 
diameter of anterior medians, laterals 0.7 
diameter. Anterior median eyes their di- 
ameter apart. Posterior median eyes their 
diameter apart. Fourth troclianter w ith two 
macrosetae on right, three on left. Abdo- 
men as in female. Total length 7.8 mm. 
Carapace 4.2 mm long, 3.6 wide. First fe- 
mur 5,1 mm, patella and tibia 6.4, meta- 
tarsus 3.2, tarsus 1.2. Second patella and 
tibia 5.1 mm, third 3.0, fourth 4,7. 

Note. The males were not collected with 
females but w ith two males of P. velutina. 
Their similarity to females in appearance 
and being collected within the same range 
suggested the match. 

Variation. Total length of females 9.6 
to 13.6 mm. The female from Bahia had 
the posterior median plate narrower than 
the one illustrated (Figs. 82, 83). Females 
from Itabapoana and Porto Cabral had the 
epigynum with a larger base relative to 
tlu* length of the scape. Both females be- 
longing to the MNRJ had their scapes bro- 
ken off. Figures 81, 82, 85, 86 were made 
from the holotype; Figures 83, 84, from a 
specimen from Sumarc, Rio de Janeiro, in 
AMNH, 

Diagnosi.s. In posterior view^ (Figs, 82, 
83), the epigynum of P. monticola has a 
round posterior median plate, constricted 
dorsally, while that of P. veliilina is very 
narrow over most of its length (Figs. 75, 
76). But there is considerable variation in 
the shape of the posterior median plate 
and the shape of its base. 

Natural History. A female was collected 



in Fspirito Santo in an orb on a shrub in 
woods, another in Itabapoana lianging on 
a thread from a leaf of a shrub in woods 
at night.

Note, There are two female syntypes 
and one al)domen. The abdomen may be 
of a different species but it may be the 
epigynum of this abdomen that was illus- 
trated by O. P. -Cambridge. Here I follow 
Keyserling (1892) and F. P. -Cambridge 
(1904), who illustrated the epigynum of a 
complete specimen (but with cephalotho- 
rax and abdomen separated). The third 
specimen, with the abdomen attached to 
the carapace, has the scape of tlie epigy- 
mmi broken. All had been on pins in al- 
cohol and are in poor condition. The pins 
were carefully removed.

Diagnosis. Females differ from those of 
P, tarapoa by having a longer scape and 
a narrower posterior median plate in the 
epigynura (Fig. 98). The male differs from 
those of similar species by the nearly round 
conductor and shorter median apophysis 
(Fig. 102).

specific name is a noun in apposition after the type 
locahty. 

Description, Female from Manaus, Bra- 
zil. Carapace orange with paired darker 
spots. Sternum dusky yellow. Coxae yel- 
lowish with dusky marks; legs hght orange 
with dusky rings, which are darker on 
proximal articles. Dorsum of abdomen with 
dark brown median band bordered by 
white (Fig, 107); venter black with a pair 
of small white spots, spots almost touching 
(Fig. 108). Tubercles of lateral eyes small 
and indistinct. Posterior median eyes 0.8 
diameter of anterior medians, laterals 0.7 
diameter. Anterior median eyes their di-

2.7, tarsus 1 .0. Second patella and tibia 3.6 
mm, third 2,1, fourth 3.4. 

Note. The male and the female were 
collected together in Manaus. 

Variation. The holotype is darker than 
the specimen described and figured (Fig. 
107) and 9.3 mm in total length. All illus- 
trations were made from specimens from 
Manaus, 

Diagnosis. The large, wide median plate 
of the epigynum (Fig. 105) separates fe- 
males of F. tarapoa from those of F. diviso- 
ria, which has a narrower median plate 
(Fig. 98). The male is separated by the 
wider base of the median apophysis and 
the slightly different shape of the embolus 
of the palpus (Fig. 109).

coxae olive-brown. Legs brown. Abdomen 
(damaged by insect pin) with trapezoidal, 
hghter area, w idest anteriorly; venter dark 
with a median light spot. Posterior median 
eyes 0.7 diameter of anterior medians; lat- 
erals 0,7 diameter. Anterior median eves 
0.6 diameter apart. Posterior median eyes 
slightly less than their diameter apart. 
Fourth trochanter with three macrosetae. 
Abdomen with five tubercles. Total length

First femur 4.9 mm, patella and tibia 6.2, 
metatarsus 5.9, tarsus 1.2. Second patella 
and tibia 3,2 mm, third 3,1, fourth 4.2. 

Note. The male and the female were 
not collected together, but they have the 
same type locality and distribution. 

Variation. Total length of females 12 to 
17 mm, of males 7.4 to 8.8. The females 
have nine or 10 tubercles on the abdomen: 
the last tubercle, the posterior median, may 
be missing. The fourth trochanter of the 
male from Sirena has two macrosetae on 
one side, three on the other. Figures 117- 
121 were made from a female from La 
Selva, Costa Rica; Fig. 122, from the ho- 
lotype of E, arniata. 

Diagnosis. Parawixia rigida differs from 
other Central American species by having 
a median white spot on the venter of the 



abdomen {Fig. 121). The female differs 
from those of P. hypocrita and P. nesophi- 
la, which also have a white spot, by having 
the scape of the epigynum long (Figs, 117, 
119, 121) and laterally flattened (Fig. 119), 
The male differs by the shape of the large 
curved median apophysis with a distal 
notch (Fig. 122).

"zwei Linien langeii, gesclnveift geboge- 
nen nadelformigen Legestachel/' Most 
other Parawixia species with a long scape 
have a more spherical abdomen. Parawix- 
ia kochi alhozonata is presumably the same 
species as the other two **subspecies'' de- 
scribed by di Caporiacco even though the 
abdomen is missing. Parawixia kochi mac- 
tililatera has the characteristic abdomen 
shape and epigynum of P. kochi, Moli- 
naranea setosa has the characteristic em- 
bolus with a round tip and neck of males 
of P. kochi. 

Description. Female syntype of E. nii- 
nas. Carapace brown, clypeus darkest. 
Sternum maculated light and dark brown. 
Legs brown, indistinctly ringed. Dorsum 
of abdomen shades of brown w ith folium 
outHned with dark (Fig, 126); venter brown 
with indistinct light patches and some 
paired white pigment patches (Fig. 127). 
Posterior median eyes 0.8 diameter of an- 
terior medians, laterals 0.7 diameter. An- 
terior median eyes slightly less than their 
diameter apart- Posterior median eyes their 
diameter apart. Abdomen longer than 
wide, w ith three pairs of lateral tubercles 
and five posterior (Fig. 126). Total length 
16 mm. Carapace 6.6 mm long, 5.4 wide. 
First femur 7.8 mm, patella and tibia 9.5, 
metatarsus 6.2, tarsus 2.L Second patella 
and tibia 9.2 mm, tliird 5.5, fourth 8.7. 

Male syntype of E. niiiias. Carapace or- 
ange, less distinctly marked than carapace 
of female. Fourth trochanter with one short 
macroseta. Abdomen oval, humps indis- 
tinct. Total Ic ngth 10,5 mm. Carapace 6,2 
mm long, 4,8 wide. First femur 6.9 mm, 
patella and tibia 8.4, metatarsus 5.2, tarsus 
1.7, Second patella and tibia 6.7 mm, third 
4.2, fourth 67. 



Variation, Some individuals have a 
spherical abdomen, but usually the abdo- 
men is longer than wide (Fig. 126), There 
alw ays are an anterior pair of tubercles and 
five posterior, with two smaller pairs on 
the sides. One female from Peru had the 
anterior lateral tubercles double. There are 
manv individual differences but there is 
no consistent geographical variation. How- 
ever, there are consistent geographical dif- 
ferences in the shape of the terminal 
apophysis, embolus, and base of the me- 
dian apophysis (Figs. 128-135). Neverthe- 
less, in all palpi the tip of the embolus is 
round and has a neck, and in all palpi the 
base of the median apophysis has a similar 
tooth pointing at the radix (Figs. 128-135), 
Total length of females 12.8 to 18.8 mm, 
of males 8.3 to lO.S. Figures 123 to 128 
were prepared from a female from the 
Meta Dept., Colombia; Figure 129 was 
prepared from a male from Guyana; Fig- 
ure 130, from the male syntype of Epeira 
tiiinas. 

Diagnosis. The female can be recog- 
nized by the long, slender scape of the 
epigynum with concave sides (Figs. 123- 
125), and usually by the slightly elongate 
abdomen (Fig, 126). The base of the epigy- 
num has two characteristic dark spots (Fig. 
123). This is the only Parawixia species in 
which the male palpus has a round em- 
bolus tip above a neck (Figs. 128-135). The 
fourth trochanter of the male almost al- 
vvavs has one macroseta; onlv one Peruvian 
male lacked the seta. 

Natural Hisfrnij. The species has been 
collected in its web at night in rain forest, 
in secondary forest, savanna, and swamp 
fore st, and also on a l)urned out tree. Spec- 
imens collected by H. Hofer near Manaus

Note. I follow Key selling in the inter- 
pretation of P. atidax, as the species was 
not illustrated by Blackwall and Black- 
walFs specimens are lost» The immature 
specimens of Epeira coronigera have the 
abdomen circular, almost as wide as long, 
and with a distinct anterior median tu- 
bercle as may be characteristic of this spe- 
cies. Mello-Leitao's A, riheiroi was perhaps 
an immature female of P. audax, having 
a soft projection in place of the future scape 
of the epigynum. Bad cocks' s immature 
specimens of F. eumeniphila have a pair 
of white spots on the venter of the abdo- 
men as do some immature P. audax and 
adult P. undulatci; they may belong to ei- 
ther this or the other species. Mello-l.citao 
(1942) correctly placed E. audax in Para- 
wixia. Bonnet {1956: 1783) erroneously 
synonymized the name Epeira duodecim- 
tuberculata Bcrtkau with Eriophora so- 
cialis [=Parawixia histriatal 

Description. Female from Pinhal, Santa 
Catarina, Brazil. Carapace orange with 
white hair and a few dark hairs; elypeus 
brown. Sternum, coxae orange; legs orange 
with dark spots. Dorsum of abdomen yel- 
lowish with brown marks (Fig, 139); ven- 
ter dusky with three pairs of small white 
spots and a white streak on each side (Fig. 
140). Cephalic area of carapace with a pair 



of swellings. Posterior median eyes 0.9 di- 
ameter of anterior medians, anterior lat- 
erals 0.9 diameter, posterior laterals 0.8 
diameter. Anterior median eyes slightly 
more than their diameter apart. Posterior 
median eyes their diameter apart- Abdo- 
men with 13 tubercles: one anterior me- 
dian, four pairs on sides and four posterior 
(Fig. 139). Total length 12.0 mm. Cara- 
pace 5.6 mm long, 4.5 wide. First femur 
5.4 mm, patella and tibia 7.2, metatarsus 
4,5, tarsus 1.7, Second patella and tibia 6.0 
mm, third 3.5, fourth 5/4, 

Male from PinhaK Santa Catarina, Bra- 
zil. Color as in female. Posterior median 
eyes 0.8 diameter of anterior medians, lat- 
erals 0,5 diameter. Anterior median eyes 
their diameter apart. Posterior median eyes 
their diameter apart. Lateral eyes 0.6 di- 
ameter apart. Fourth trochanter without 
macroseta. Second and third femora with 
ventral row of strong macrosetae, first and 
fourth with two rows. Abdomen \^ ith 13 
tubercles as in female. Total length 8,4 
mm. Carapace 4.1 mm long, 3.7 wide. First 
femur 4,1 mm, patella and tibia 5.6, meta- 
tarsus 3.3j tarsus 1.3. Second patella and 
tibia 4.5 mm, third 2.5, fourth 3.7. 

Variation, The anterior, median tuber- 
cle of the abdomen is frequently missing. 
Some females have the anterior lateral tu- 
bercles double. The photograph of a fe- 
male from S of Jujuy, Argentina, shows 
her to be mostly green and white with 
some brown spots and brown patellae 
matching the lichens of the substrate. Im- 
matures may have a pair of white patches 
on the venter of the abdomen. Total length 
of females 10,0 to 20.8 mm; of males 7.7 
to 9.6, Figures 136-139 were made from 
specimens from Canela, Rio Grande do 
Sul, Brazil; Figures 140-142, from Pinhal, 
Santa Catarina, Brazil. 

Diagnosis. Females differ from those of 
P. bistriata by having distinct tubercles on 
the abdomen (Fig. 139), from those of F. 
undulata by having the posterior median 
plate of the epigynum swollen, sclerotized, 
and dark in color (Fig, 137), and from 
those of both by the pattern on the venter 



38 Bulletin Museum of Comparative Zoology, Vol 153, No. 1 



of the abdomen (Fig. 140), Males differ 
from most species of Parawixia by lacking 
macrosetae on the fourth trochanter, from 
P. bistriata by having tubercles on the ab- 
domen, and from both P. bistriata and P. 
tindiilata by the shape of the base of the 
median apophysis and the shape of the 
terminal apophysis of the palpus (Figs. 141, 
142). 

Natural History. This is perhaps the most 
common araneid orb weaver in southern 
Brazil. I made the following notes on 22 
March 1985 at Cataratas do Iguagu, Brazil. 
This Parawixia is very common and makes 
an enormous web, with a bridge about 2 
m long, the web 50 to 90 cm in horizontal 
diameter, with very loose, w ide mesh (Plate 
1). The bottom of the orb is about 1 to 2 
m above the ground. The spider hangs in 
the middle, cephalic region down (Plate 
1), or hides in a silk retreat within a curled 
leaf near a radius or a frame line. The 
spider walks to the retreat when disturbed 
and if touched tliere, drops slowly on a 
thick silk rope. If handled the female tries 
to throw silk on the hand. 1 watched in- 
dividuals feed on grasshoppers 3.5 cm long, 
longer than the spider. The viscous silk is 
very sticky. No two specimens have the 
same dorsal coloration of the abdomen or 
similar humps; the reddish and green col- 
oration of some individuals is w ashed out 
in alcohol. The spider is probably mostly 
nocturnal and builds at night. 

Distribution. Amazon area to Chubut 
Province, Argentina (Map 3).

Diagnosis. Females differ from those of 
P. histriata by having tubercles on the ab- 
domen {Fig. 146), from those of F. audax 
by having the posterior median plate of 
the epigynum not selerotized, flat, and 
usually white (Fig. 144), The venter of the 
abdomen, unhke that of P, histriata and 
of adult P. audax, has a pair of white 
patches on black (Fig. 147). Males differ 
from those of P\ histriata by having tu- 
bercles on the abdomen and from males 
of P. bisiriata and P, audax by the shape 
of the terminal apophysis and the proximal 
end of the median apophvsis (Figs. 148, 
). 

Natural History, One female from Sao 
Paulo State came from a shrub in a field 
along the road; the web was 40 cm in di- 
ameter. 

Distribution. From Sao Paulo State, 
Brazil, to Buenos Aires Province, Argen-

Note. Rengger gave the name ^^ Epeira

Epeira bistriata has never been illustrated 
before. According to Rengger its main 
characters are that it is a "social Epeira 
with a hazelnut-shaped abdomen having 
red spots." Only one species fits this de- 
scription, the one illustrated here. Reng- 
ger's specimens are not in NHMB or in 
the Naturmuseum Aarau, Switzerland (R. 
Maurer, C. Stocker, personal communi- 
cation).

C. L. Koch's Epeira hicolor (Fabricius) 
is a large spider from BraziL Critical fea- 
tures are a spherical abdomen with trans- 
verse marks, no distinct marks on the un- 
derside of the abdomen and a S-mm-long 
scape C'2 Linien langen, uber dieselbe 
ruck warts gebogenen Legstacher). This 
fits Farawixia bistriata. But this is proba- 
bly a misidentification of Aranea hicolor 
Fabricius (1798: 230), which has a worth- 
less, unrecognizable description of a spider 
from "America." Aranea hicolor Fabricius 
(1798) is also a junior homonym of Ara- 
nea hicolor Olivier (1789: 230). Olivier 's 
Aranea hicolor is a worthless description 
without a holotype for a spider from Gua- 
deloupe, Lesser Antilles (see also Petrunke- 
vitch, 1911). 

Holmberg (1874) writes that the scape 
of E. burmeisteri reaches the center of the 
spinnerets. This is characteristic for this 
species, but not known for any others. Me- 
Ilo-Leitao (1932) thought Burmcistrr'sand 
Holm berg's descriptions fit a diiierent so- 
cial species, common in Argentina. This 
could not be verified. 

The spider is known in Spanish as the 
*'nanduti'' spider, derived from the word 
for "spider-web" in the Guarani language 
(Fowler and DiehL 1978; Kochalka, 1989, 
personal communication), in Portuguese as 
aranJia do cerrado (C. Sandoval, 1990, 
personal communication). 

Description. Female from Depto. Cen- 
tral, Paraguay. Carapace with dark orange 
cephalic region, sides of carapace red- 
brown; cephalic region with long white 
liairs. Sternum dark orange. Coxae dusky 
dark orange; legs orange-brown. Dorsum 
of abdomen dark gray with indistinct fo- 
lium (Fig. 153); venter dark gray with in- 
distinct paired lighter patches (Fig. 154). 
Posterior median eves 0.7 diameter of an- 
terior medians, laterals 0,6 diameter. An- 
terior median eyes 1.3 diameters apart. 
Posterior median eyes their diameter apart. 
Lateral eyes their diameter apart. Abdo- 
men spherical, without tubercles (Fig, 153). 
Total length 22 mm. Carapace 9,4 mm 
long, 8.1 \\ ide. First femur 8.8 mm, patella 



and tibia ILl, metatarsus 7.1, tarsus 2.7. 
Second patella and tibia 10.5 mm, third 
6.5, fourth 9.6. 

Male from Formosa, Argentina. Darker 
than female in coloration. Posterior me- 
dian eyes 0,7 diameter of anterior medi- 
ans, laterals 0.6 diameter. Anterior median 
eyes their diameter apart. Posterior me- 
dian eyes their diameter apart. Laterals 
their diameter apart. Palpal patella with 
one dark macroseta and one light-colored 
smaller seta. Fourth trochanter without 
macroseta. Abdomen ovah Total length 13 
mm. Carapace 7,7 mm long, 6.7 wide. First 
femur 7.5 mm, patella and tibia 9.4, meta- 
tarsus 5.9, tarsus 1.8. Second patella and 
tibia 7.6 mm, third 50, fourth 7,1, 

Variation. Total length of females 16.7 
to 27 mm, of males 1 1.7 to 18.5. In adult 
females preserved in alcohol the abdomen 
is variable in color. In immature specimens 
the abdomen has a diagnostic pattern and 
three to four pairs of lateral tubercles, and 
two posterior, median tubercles {Fig, 157). 
The tubercles may be visible on the ab* 
do men of males. Early in stars are almost 
all black; later instars have light stripes, a 
longitudinal row of dark red dots on the 
tubercles on each side, and a faint red spot 
in the cardiac area. Adults are mostly dark 
gray with a little red anterior lateral on 
the abdomen dorsum (Kochalka, 1989, 
personal communication; and color pho- 
tographs by C. P. Sandoval, Plate 1). Fig- 
ures 150, 151 were prepared from the ho- 
lotype of £. aeronavis. Figure 152 was 
made from a female from Tucuman, Ar- 
gentina, 153-155 were made from syn- 
types of A. nordenskioldi^ and 157 was 
prepared from an immature from Barra 
da Tapirape, Ma to Grosso, Brazil. 

Diagnosis. Females differ from those of 
P. audax and P. undulata by having a 
spherical abdomen sometimes with only 
three faint pairs of lateral tubercles, in- 
distinctly marked on the venter (Figs. 153, 
154). The scape of the epigynum is less 
sclerotized than in P. audax and P. un- 
dtdata and the posterior median plate may 
be white (Fig. 151). Males differ from those 



Parawima •Levi 



43 



of the similar two species by having a prox- 
imal constriction of the median apophysis, 
and l>\ the shapes of the base of the median 
apophysis and the distal end of the ter- 
minal apophysis (Figs. 155. 156), 

Natural History, The species has com- 
mnnal webs 2 to 5 m above the ground, 
just beyond reach, often on telephone poles 
in urban and suburban areas, in open 
woodland and orchard, in the lower Pan- 
tanal, and in isolated trees in drv areas, 
but never in a forest having a closed can- 
opy- Individuals cluster during daytime in 
a common shaded retreat ''as big as a hat," 
constructed with relatively little silk (Plate 
1). At dusk the spiders move out on thick 
silk lines that stretch as far as 30 m and 
build orbs. Within an hour all orbs are 
completed, and may cover a 100 m- area. 
The orbs are taken down at daw n. Marked 
spiders do not return to the same spot as 
that of the previous night, but build in the 
vicinity. Large prey ensnared are over- 
powered and fed on by many spiders, the 
number in proportion to prey size. Repro- 
ductive casts of ants are a common prey 
item, but are not the onlv food. All spiders 
in a colony are of the same age and molt 
during the same week. Spiders transferred 
to another colony are not attacked and 
neighboring colonies may fuse. Males and 
females mature in late January in southern 
Brazil The number of males is approxi- 
mately equal to that of females. Following 
the final molt, females disperse and deposit 
egg'Sacs w ith a mean of 551 eggs, less than 
half the number laid bv related araneids 
of equal size. Spiderlings emerge in May. 
In the laboratory there are eight postem- 
l)ryonie ins tars. (J. Koch a Ik a, C, Sandoval, 
personal communications; Fowler and 
Diehl, 1978; Fowler and Gobbi, 1988a,b). 
Rengger gives colony size as between 30 
to 40 individuals; Azara in 1808 estimated 
less than 100 individuals (Fow ler and Diehl, 
1978; Kochalka, 1989, personal commu- 
nication). In 1965, when visiting Rio de 
Janeiro, I saw what 1 believed to be webs 
of this species, high up on telegraph poles 
outside the entrance of the Parque da Ci- 



dade. too high up to collect, I could not 
find any webs on a return visit to the same 
spot in 1987. Carter (1928) claims that the 
spiders' bite is venomous. They can kill 
beetles larger than 2.5 cm in a few minutes 
and thert^ are records of birds trapped in 
their webs (C. Sandoval, personal com- 
mLinication). 

Venom. The Hospital Vital Brazil of the 
Institute Butantan has recorded only three 
accidents, all of persons living in the area 
surrounding the city of Sao Paulo: In 1964, 
a 7-year-old girl was bitten on the hand 
with only slight pain. In 1966, an 18~year- 
old man was bitten on the foot; no treat- 
ment was necessary. In 1970, a baby of 
eight months was bitten on the buttock 
w ith moderate local pain, edema and mild 
erythema. In all cases punctures of fangs 
w ere visible. The first and last victims were 
treated with antihistamines and analgesics. 
Vellard, in his book on spider venoms 
(1936: 262), did not cite anv accidents with 
the species, but expressed the belief that 
they do occur and are not serious. In recent 
years, V. P. D, von Eickstedt has received, 
from the Sao Paulo State Central Electrical 
Co. from Andradina and from Pirassunun- 
ga, requests for help in removing the spi- 
ders because workers were afraid to work 
on poles with webs (Vera 1\ D. von Eick- 
stedt, 1990, personal correspondence).
